CAT6a vs CAT6 RJ45 plugs

Fair comment. 4Gbps is still a huge amount of bandwidth. Can I ask what is it you do that requires it?

ChuckMountain

HDBaseT running at 1080p60 would be more than 1Gbps of traffic it is around 4.46Gbps?

Why are they only getting 7Gbps?  It does not have a speed drop off with distance unless you are physically losing packets on the way and requesting retries.  Surely it would be more a question of the equipment not being able to keep up?


Optical is pretty flexible and these days can be quite cheaper, some argue cheaper and more energy-efficient than copper when you take the rest of the bits into consideration.

If you are directly connecting to a switch etc how do you ensure that the drain wire is only connected at one end?  I am pretty sure the majority of pre-made cables the shield and drain wire are connected at both ends

Patch cables have the drain wire connected at both ends but the structured cable normally has the drain wire only connected at one end, normally the patch panel, which is then itself normally connected to a permanent ground via the grounding lug. The patch panel connected by Cat 6a patch cables to the switch, which ensures that the switch is adequately grounded too.
Connecting both ends of the structured cable at both ends risks setting up ground loops, especially if going from one building to another, that have different earths.

Not sure about the energy efficiency, as that’s not really important to me. I’d be looking at a 50m fibre cable I think and when I looked that was very expensive. Plus the transceivers/SFP  modules and it far outweighed the cost of some CAT6a. The new switches I am looking at have 10GB RJ45 ports.

Both buildings have the same earth in my situation

You’ll still need a to ensure that your Cat6a infrastructure has a good dedicated ground.

I agree, just saying

I am upgrading some of my network to 10Gbit just looking at the most efficient way of doing it.  When looking switches that have SFP  are generally cheaper than Ethernet equivalent ones.  The Ethernet ones used a reasonable amount per power and 10W for example is an extra tenner a year in juice usage.

What switches and NICs were you thinking of going for out of interest?

Puntoboy

NICs I hadn’t decided on yet but I was looking at the Mikrotek switch at the main one In the house. It was in another thread.

Could you recommend a link to fibre cables, please? Maybe the ones I were looking at were a stupid price.

I am also looking at the Mikrotik switches and possibly a router but they have a lot of vulnerabilities in their RouterOS so it is a bit off-putting at the moment.

I was looking at generic cable albeit not 50m though even that isn't too much. Lindy have some at £36 for 50m but haven't checked that.  Some generic SFP  modules also were pretty cheap.  This combined with some SFP  cards (mellanox connectx-3) which can be sourced off eBay at a good price.
